Wax Saturated Boxes Our wax saturated boxes are the toughest most reliable design available on the market. The boxes are made of special water-resistant materials that are placed under 3 cascades of hot wax, completely enveloping the box creating a wax shell on the inside, outside, and throughout all interior corrugated flutes. There are other wax treatments available but we have found none as effective as our wax saturation.
